Overview
Wastewater treatment is generally divided into 2 different categories, sewage treatment and greywater treatment. Sewage treatment, also known as blackwater, encompasses all waste water that is generated by residential, institutional, commercial and industrial establishments. It includes household waste liquid from toilets, baths, showers, kitchens, and sinks draining into sewers. In many areas, sewage also includes liquid waste from industry and commerce.
Greywater, on the other hand, is a subcategory of sewage and treated completely differently to general sewage. It is all wastewater generated in households or office buildings from streams without fecal contamination. The separation and draining of household waste into greywater and blackwater is becoming more common in the developed world, with treated greywater being permitted to be used for watering plants or recycled for flushing toilets
